TLDR
The general trend has been one of increasingly complex catalyst formulations in response to increasingly stringent emission standards as discussed by the authors, but with greater emphasis on optimizing catalyst formulations for lean-burn applications and reducing catalyst cost and complexity without sacrificing performance.About:

Search for high-capacity oxygen storage materials by materials informatics
TL;DR: In this article, a support vector machine regression model was trained to predict the oxygen storage capacity (OSC) of 60 metal oxides from the amount of CO2 produced under alternating flow gas between oxidizing (O2) and reducing (CO) conditions at 973, 773, and 573 K.

Catalysis by shapely nanocrystals of the Ce1−xYbxO2−x/2 mixed oxides — Synthesis and phase stability
TL;DR: In this paper, the shape and structural stability of octahedral ceria-based mixed oxides with increasing Yb content was investigated and it was observed that the predetermined shape of the investigated samples was kept up to x 0.2.
Journal ArticleDOI
Investigation of the Thermodynamic Properties of Surface Ceria and Ceria–Zirconia Solid Solution Films Prepared by Atomic Layer Deposition on Al2O3
TL;DR: In this article, the properties of 20 wt % CeO2 and 21 wt% Ce0.5O2 films, deposited onto a γ-Al2O3 by Atomic Layer Deposition (ALD), were compared to bulk Ce 0.5Zr0.75 phases.

Binary Oxides Prepared by Microwave-Assisted Solution Combustion: Synthesis, Characterization and Catalytic Activity.
Kawthar Frikha,Lionel Limousy,Jamel Bouaziz,Kamel Chaari,Ludovic Josien,Habiba Nouali,Laure Michelin,Loïc Vidal,Samar Hajjar-Garreau,Simona Bennici +9 more
TL;DR: With a CO conversion of 100% at 225 °C, the copper containing catalyst showed a much higher activity than that usually measured for catalytic materials of similar composition, thus representing a promising alternative for oxidation processes.

Catalysis by Ceria and Related Materials
TL;DR: The use of ceria-based catalysts in automotive catalysts was discussed in this paper, where the authors showed that the properties and thermal stability of Ceria-zirconia and related materials can be characterized using surface analysis techniques.

Rh-Loaded CeO2-ZrO2 Solid-Solutions as Highly Efficient Oxygen Exchangers: Dependence of the Reduction Behavior and the Oxygen Storage Capacity on the Structural-Properties
Paolo Fornasiero,R. Dimonte,Gangavarapu Ranga Rao,Jan Kašpar,S. Meriani,Alessandro Trovarelli,Mauro Graziani +6 more
TL;DR: In this paper, it is shown that incorporation of ZrO2 into a solid solution with CeO2 strongly promotes bulk reduction of the Rh-loaded solid solutions in comparison to a Rh/CeO2 sample.

Twenty-five years after introduction of automotive catalysts: what next?
TL;DR: The union of catalysts and the automobile has been one of the greatest successes of heterogeneous catalysis over the last 25 years as mentioned in this paper, and there will be continued research and development activity focused also on downstream applications (i.e. exhaust emission aftertreatment), especially for fuelefficient, lean-burn vehicles, both diesel and spark-ignited.
